Vote count:

I can set the size of the area of influence of a positional light? Something like the image:

I do not know if I can do this with GL_CONSTANT_ATTENUATION, GL_LINEAR_ATTENUATION and GL_QUADRATIC_ATTENUATION.

Since I have not seen documentation that talks about this and what values ​​should each option.

Thanks.
